Typedef Documentation

typedef std::map< std::string , std::map<types::boundary_id, double> > component_boundaryID_value_map

The typedef for the std::map that reflects the following structure:

• first argument : name of the solution component,
• second argument : boundary id,
• third argument : value of the solution component.

typedef std::map< std::string , std::map<types::material_id, double> > component_materialID_value_map

The typedef for the std::map that reflects the following structure:

• first argument : name of the solution component,
• second argument : material id,
• third argument : value of the solution component.

This map is usually used to initialize the solution of the problem. If you would like an initial solution that is different for each matrial id, you can specify this here. For example, imagine I want to specify for material_id 0, an oxygen molar fraction of 0.1 and for material_id 2, an oxygen molar fraction of 0.2. Then, I would write

* std::map<types::material_id, double> values;
* values[0] = 0.1;
* values[1] = 0.2;
* component_materialID_value_map['oxygen_molar_fraction'] = values;
* 

In general, this object is initialized directly from the input file in the Equations section of the data file. For example, in the input file if I write:

* subsection Equations
*   subsection Ficks Transport Equation - oxygen
*     subsection Initial data
*       set oxygen_molar_fraction = 0: 0.1, 1: 0.2
*     end
*   end
* end
* 

This would be equivalent to the code above.
